CHARLES A. BARTLOG, OF MILWAUKEE, WISCONSIN MUD-GUARD FOR CRANKING- DEVICES.

Specification of Letters Patent.

Patented Feb. 24., 1914.

Application filed March 17, 1913. Serial No. 754,869.

To all whom it may concern:

Be it known that I, CHARLES A. BARTLOG, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented certain new and useful Improvements in Mud- Guards for Cranking Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in mud guards or casings and relates more particularly to those which are especially adapted for use in connection with cranking devices for internal combustion engines of that type which is shown in my pending application, Serial No. 752,512, filed March 6, 1913.

The primary object of the invention is to provide a mud guard or case which shall be of extremely simple construction, cheap to manufacture, and which may be very readily assembled about the device which it is designed to protect.

Another and more specific object of the invention resides in the provision of a mud guard of this nature, which will be rotatable with the starting shaft, and which will also serve to brace the same as the engine is being cranked.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a side elevation, showing one section of my improved mud guard positioned about the cranking device, and, Fig. 2 is a front elevation.

Referring in detail to the drawings by numerals, 5 designates a starting shaft of an engine which is actuated by my improved cranking device described and claimed in the above referred to application. Generally speaking, this cranking device comprises a cylindrical casing 6, which is rigidly secured in position by suitable means. The starting shaft 5 is slidable through and rotatable within the casing 6 and carries upon its outer end a cam 7. An operating member 8 is provided and carries a crank handle 9, said operating member being rotatable with the shaft 5. To crank the engine the operating member 8 is forced inwardly and then rotated. Should the engine back fire, the

pin 10 which projects through the operating member 8, engages the face'of the cam 7 and separates the shafts.

My improved mud guard is especially adapted for use in connection with the above described structure and is formed in two sections 11 and 12. When these sections are secured to one another, they form two cylindrical chambers, designated respectively,

3 and 14:. The chamber 13 is formed by a rim 15 and a front wall 16, said wall being centrally apertured, as indicated at 17. The chamber 13 is open alongits'inner side and is adapted to receive the stationary casing 6 when the engine is being cranked.

The chamber 14: comprises a peripheral wall 18, which extends outwardly from around the opening 17, formed in the front wall 16 of the first mentioned casing. An end wall 19 closes the outer end of the chamber 14. The wall 18 is formed at diametrically opposite points adjacent its inner end with openings 20 through which the operating member 8 passes.

Ears 21 and 22 are formed upon the sec tions 11 and 12, respectively, and are aper tured to receive the fasteners 23 by means of which the two sections are secured to each other.

It will be seen from the foregoing descrip tion taken in connection with the accompanying drawing, that I have provided a mud guard or casing which may be easily cast, which may be quickly secured in operative position around the cranking device, and which will effectually protect the latter from any foreign substances.

It will be noted upon reference to Fig. 1 that since the inner surface of the rim 15 is always in engagement with the periphery of the casing 6, the casing acts as a brace for the cranking device.

Having thus described my invention, what I claim is 1. The combination with a cranking device for internal combustion engines, including a stationary casing, a starting shaft slidable theret-hrough, and an operating member rotatable with the starting shaft; of

a mud guard adapted to surround said casing and starting shaft, the mud guard being formed in sections and comprising two chambers of different diameters, the peripheral wall of the smaller of said chambers being cut away to permit the passage therethrough of the operating member.

2. The combination with a cranking device for internal combustion engines, in-V eluding a cylindrical stationary casing, a starting shaft movable longitudinally through said casing, an elongated operating member rotatable with said starting shaft, and means for moving the starting shaft longitudinally when the engine back fires;

of'a mud guard, said guard comprising a cylindrical chamber open at one side to receive said stationary casing, the other side of said guard being centrally apertured, and a second cylindrical chamber extendin laterally from the apertured wall and being cut away to permit the passage therethrough of the operating member.

In testimony whereof I afiix my signature in presence of two witnesses.
